Casio G-Shock Classic GM-2100LXB-1AER

The G-SHOCK Classic Series GM-2100LXB-1AER reinterprets the popular 2100 series through a modern, sophisticated LUXE BLACK concept. The watch has been stripped of all unnecessary embellishments and focuses on disciplined minimalism, creating a timeless quality. Deep black tones and subdued contrasts build on G-SHOCK's legendary durability, providing the watch with a calming presence and a controlled shine.

The watch's sophisticated nature is emphasized by its matte black dial, whose fine texture absorbs light and prevents reflections. Redesigned, slim and longer hour and minute hands are combined with elegant, vacuum-deposited indexes, balancing legibility with high surface quality. The whole is deepened by the silver details of the small dial and the vacuum evaporation on the glass rim, which emphasize the sophisticated and deep interaction of the materials.

In terms of materials, the GM-2100LXB combines a black ion-plated steel bezel and a black resin bracelet. The watch is equipped with the shock-resistant structure characteristic of G-SHOCK and the protection offered by the incredible 200-meter water resistance. Practicality for everyday life is brought, among other things, by the hand shift function, which moves the hands out of the way of the digital display when you want to read it without obstruction. The dual LED light (Super Illuminator) with a bright white tone ensures that both the analog dial and the digital display are readable in complete darkness.
